AI Technical Summary
Traditional buckling-restrained braces (BRBs) have inconsistent load-bearing capacity deformation curves with the reinforced structural layers, making it difficult to precisely match multi-level seismic resistance requirements and limiting their adjustment, thus hindering rapid replacement in the event of earthquake damage.
The design employs multiple BRB parallel units, and through modular connection components and adjustable connecting screw lengths, it achieves multi-segment bearing capacity-deformation relationships. Combined with modular design and quick disassembly of knob nuts, it ensures that the support structure maintains stable performance and can be flexibly replaced under different seismic intensities.
It achieves precise matching of inter-story stiffness and bearing capacity under multi-level earthquakes, improves the seismic performance and toughness of the structure, reduces maintenance costs, and enables rapid replacement of damaged units after an earthquake.
